Canon EOS350D USB does not work for users: ------------------------------------------ On Debian, it seems that a normal user does NOT have the ability to use the Canon EOS350D via the USB ports. Gotcha: ------- You probably forgot to add Your normal users to the camera group. There might not even BE a camera group, in which case You need to add it to the system. As a workaround, You could change the hotplug system. Specifically, You need to change the libgphoto2 hotplug script "/etc/hotplug/usb/libgphoto2", and change the group in the script to another group that should be allowed to access the camera.
